This is a lego GBC (Great Ball Contraption) miniloop, it is a smaller version of a full-scale GBC module. It is the perfect size to keep on your desk and it can be powered by a motor or a hand crank. I built it because I wanted it to be easier for people to get into building great ball contraption modules, as it can be quite hard to build your first module by yourself.
